Tips: Sealing Technology of Sewage Pump
The so-called auxiliary impeller hydrodynamic seal refers to the installation of an open impeller in the opposite direction near the rear cover of the impeller of the pump. When the pump works, the auxiliary impeller rotates with the pump spindle, and the liquid in the auxiliary impeller will rotate together. The rotating liquid will produce an outward centrifugal force, which on the one hand resids the liquid flowing to the mechanical seal and reduces the pressure of the mechanical seal.
On the other hand, it prevents the solid particles in the medium from entering the friction pair of mechanical seal, reduces the wear of the grinding block of mechanical seal, and prolongs its service life. In addition to sealing, auxiliary impeller can also play a role in reducing the axial force.
